Tool for removing mandrel mounted disks

Abstract

A base supported tool having a holder with one jaw of the holder slidably carrying a screwdriver. The remaining jaw is recessed to receive the mandrel of a powered handpiece. A plate on the jaw is also recessed and has flats to engage flats on the mandrel to hold the latter against rotation during removal of a mandrel screw. A pin supports the plate for limited rocking motion to facilitate mandrel entry into the recess. The holder may pivot also for the purpose of mandrel entry into the plate recess.

I claim: 
     
       1. A tool for temporarily holding a handpiece mounted mandrel against rotation during mandrel disassembly, said tool comprising, a base,   a holder supported by said base and defining a bite area adapted for reception of a mandrel end,   a plate on said holder having planar surfaces defining an upwardly opening recess with said surfaces adapted for abutment with flats formed on the mandrel to hold the latter against rotation,   pin means coupling said plate to said holder in a manner permitting limited rocking motion of said plate to facilitate mandrel reception, and   a screwdriver slidably mounted in said holder and adapted for axial engagement with a screw on the mandrel end to remove a mounting screw thereon preparatory to removing a disk from said mandrel.   
     
     
       2. The tool claimed in claim 1 wherein said holder limits rocking movement of said plate. 
     
     
       3. The tool claimed in claim 1 wherein said base additionally includes a post, said holder swingably carried by said post for holder travel in a horizontal plane to facilitate holder alignment with a handpiece mandrel. 
     
     
       4. The tool claimed in claim 3 wherein said holder is supported in cantilever fashion by said post.
